A laboratory version of a fluorosensor consisting of a 5-kW nitrogen laser, an 8-inch f/10 Cassegrainian telescope fitted with an RCA C31005C photomultiplier, and readout electronics, was assembled and tested. Detection sensitivity of the system was measured using two different combinations of optical filters, one primarily for daylight use and one exclusively for nighttime operation. System sensitivity was measured using a standard quinine bisulfate solution (in 0.1 N H/sub 2/SO/sub 4/); the smallest concentration that could be detected was 8.0 x 10/sup -7/ g/l with the nighttime set and 9 x 10/sup -5/ g/l with the daytime set. A concentration of 9.8 x 10/sup -6/ g/l was detected using the daytime set at night. The fluorescence of effluents from several DOE coal treatment facilities was also measured.
